Solution Overview

Problem

Unattended item deliveries often result in inefficiencies, potential damage, theft, or unauthorized access due to the lack of secure and efficient mechanisms for ensuring only authorized parties gain access to the delivery location.

Innovation Solution

A remote access system that verifies the presence of an expected item at an expected location with expected monitoring before granting access, using a delivery device to scan an item, confirm proximity via Bluetooth Low Energy, and transmit requests through a network to unlock the delivery location securely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the item is left unattended at the delivery location, then the delivery process is simplified and faster, but the item may be damaged, stolen, or accessed by unauthorized persons

Engineering Contradiction:
Improvedelivery efficiencyVSAvoiddelivery security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

A remote access system acts as an intermediary between the delivery agent and the secured location. The system receives authentication credentials, verifies authorization, and controls access to the delivery location through electronic locking mechanisms, enabling unattended delivery while maintaining security through automated verification and monitoring

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary authentication and authorization checks before granting access to the delivery location. Credentials are verified in advance, and access decisions are made automatically before the delivery agent physically enters the secured area, ensuring security protocols are followed without manual intervention during the actual delivery

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a person is present to receive the item, then delivery security is ensured, but the delivery process requires coordination and may be delayed

Engineering Contradiction:
Improvedelivery securityVSAvoiddelivery time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The delivery location is equipped with automated access control systems that self-verify credentials and automatically grant or deny access without requiring a person to be present. The system independently handles authentication, authorization, and access control, eliminating the need for coordination with recipients while maintaining security

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Authentication credentials are verified in advance of the actual delivery moment. The system pre-authenticates delivery agents and pre-approves access requests, so that when the delivery agent arrives, access can be granted immediately without waiting for recipient presence or manual verification

Inventive Principle:
Principle #10Preliminary action

3Productivity

If multiple access attempts are made when no one is available, then the item may eventually be delivered, but time is lost and the process becomes inefficient

Engineering Contradiction:
Improvedelivery completionVSAvoiddelivery time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The automated access control system continuously monitors for available recipients and independently manages multiple access attempts without requiring human intervention. The system can retry access, notify recipients, or secure the location automatically, ensuring delivery completion while minimizing time loss through automated decision-making

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements periodic access attempts at predetermined intervals when initial delivery attempts fail. Automated notifications are sent at regular intervals, and access requests are retryed systematically, ensuring eventual delivery while optimizing the timing and frequency of attempts to minimize overall delivery time

Inventive Principle:
Principle #19Periodic action

AI summary

Features are disclosed for accurately authenticating a delivery agent for unattended delivery of an item. The systems and methods described confirm the location of the delivery agent and proximity to the delivery location using short range wireless communications between a monitoring device at the delivery location and a communication device associated with the delivery agent. Access may also be conditioned on user specified "do not disturb" rules indicating when remote access is authorized. The authentication may be dynamically assessed such as based on a type of item being delivered.
